okay, so at 50k as far as maintenance goes I have only done oil changes and oil filter and air filter. Am I missing something? Because lately I feel like I am loosing little of her old kick. Thanks in advance for helping me.

 

check your throttle body? May need a cleaning, get some throttle response.

 

Yeah I forgot to add I did that, but it has been around 20k since I did that. I should prob do that again.

 

Trans, front and rear diff flushes, plugs/wires, check the battery.

 

Dang, can I do all that myself?

 

Wow, you've never done any differential fluid changes....yikes.... Transmission is due for a flush as well. Your lucky you only have the rear differential because 4wd's need the transfer case, front and rear diff fluid changes every 30kmi.
Your 20kmi past due.

You can go to any quick lube and they can do it about 30 minutes. Much easier than crawling under your truck yourself if you just don't know how. You'd be saving only $30 if that by doing it yourself. They can do the tranny flush at the same time. You couldn't do a proper fluh yourself, but only a drain and refill. That only gets half of the fluid. The other half is in the torque converter. They have a special machine that pushes all the old fluid out with the new fluid. It's well worth the expense! They only touch the lines going to your radiator, they do not pull your pan. I reccomend pulling the pan and doin a filter change the next time around for sure.
Also, Plugs are every 30kmi so I'd change those plugs and you ight get some kick back. Wires should be fine for now.
Fuel filter should be changed and I'd drop in a small bottle of Lucas Injector cleaner.

 

FYI...i just did a trans service at 39500 miles and the truck shifts much better, before it was slow to shift and would hunt alittle for the right gear. Definatly money well spent.

 

Thanks for all the info guys. I really appreciate it.
